Abstract

This paper presents a simple electronic starter for single phase induction motor (SPIM). It replaces the centrifugal switch in the auxiliary winding circuit of the capacitor start type SPIM. The centrifugal switch disconnects the auxiliary winding when the motor gets close to its rated speed. The presence of the centrifugal switch, with its possibly fluttering contacts, reduce reliability of SPIM. The operation principle of the proposed electronic starter is explained, and illustrated with experimental results.
